TIRE-TREATING APPARATUS.

Application filed May 29, 1923. Serial No. 642,269).

To all whom it may concern:

Be it known that I, H'noron V. Loncn, a subject of the King of. En land,residing at Hartford, county of Hart 0rd, and State of -Connecticut,have invented a certain new and useful Tire-Treating Apparatus, of whichthe following is a full, clear, and exact description.

This invention relates to the manufacture of tires and, moreparticularly, an apparatus for facilitating a treatment of the casingssometimes: desirable in their manufac- In connection with what is knownas the p)ulley-band process of manufacturein w ich the casings are builtfiat on a drum and then roughly brought to tire form by pressing theirbeads together while simultaneously bulging out the Central portion ofthe bandit has been found desirable, before Curing the casings, tosubjectthem to a setting treatment. The casings are confined insectional molds, much like those used in finally vulcanizing them, and afluid pressure of around 200poundsa lied (usually through a rubber bagresem b ing an inner tube) to the inner walls of the casing,- thesections of the mold being suitably held to ther, by clamps forinstance.

e present invention aims to provide a simple and easily manipulatedapparatus for introducing and removing the casings incident to theabove-mentioned set treatment, in which, ordinarily, no heat isemployed. Various advantages of the invention will be inafter given.

With the illustrated embodiment in mind and without intention to limitmore than is required by the prior art, the invention consists briefi'in su porting the shaping molds-as t e are ca edso that they may beopened boo -fashion without arduous labor vand with a rapidity meetingeconomic re uirements.

preferred embodiment of the invention is illustrated in the accompanyingdrawings in which Figures 1 and 2 are elevation and plan views,respectively, of the apparatus locally :ectiond to disclose details ofthe construcion;

Figure 3 is an end elevation of the same;

And Figure 4.- is an enlar ed detail, partly in section, illustratinggui eways, supporting rollers, and a rack, constituting portions of thereferred apparatus.

According to the invention, one or more .molds, each having a pair ofsections 1 and raz1 2, are secured by ng or bolting to cradles 3 and 4:,which are hinged together, as at 5, to insure the sections of the moldregistering when closed together and also to enable the two sections ofeach mold to be manipulated rapidl and as a unit. Each of the cradles 3an 4 is provided with a pair oflugs 5-6 and 7-8, these lugs beingpreferably located, as shown, at or approachin a diameter through themold sections whic is parallel to the hinge-pin 5', and desirablydividing the weight of the mold sections so as to facilitate theswinging of each as the sections are spread apart. The lugs 7-8 are eachequipped with rollers 9 and 10, respectiveiy, which rest upon a pair ofupper guideways 11, which are fashioned on the parallel sides of aframe, indicated generally by the numeral 12. The frame 12 ma be of anysuitable construction but is pre erably braced by stays 13, atintervals, which maintain it rig1d and the guide-ways 11 parallel to oneanother.

The lugs 56 also are each equipped with rollers 14 and 15, respectively,preferably having roller-bearings (not shown).

preferred to employ a grappling device, in-

dicated generally by the numeral 24, which is constructed as fullydisclosed in my copending application Serial No. 642,270, filed May29th, 1923, this grappling device bein supported on a carria e 25, whichtrac s an Ibeam, or other sultable len hwise extending su port, 26,sustaine in spaced relation an preferably parallel to the guideways 11by standards 27 and 28 secured to the op osite ends of the frame 12.

The invention 1s not intended to-be' limited to details of theconstruction disclosed v and reference should be made to the appendedclaims for an understanding of its scope.

Having thus described my invention, what I claim and desire to protectby Letters Patent is 1. An apparatus for treating tires comprising, incombination, a plura ity of molds each consisting of a pair of sectionshinged together,-;, and,means for supporting the sections of said moldspermitting them to be shifted-and opened book fashion each moldindependently of the others,

2Q Anapp'aratus for treating tires comprising, in combination, aplurality of hinged sectional molds, means for supportin thesections ofsaid hi1! e'd molds permitting them 7 to l)e ,.ope'ne book-fashion, saidmeans including rollers sustaining the respective mold sections atopposite sides of each, and runways for said rollers.

3. An apparatus for treating tires comprising, in combination, aplurality of hinged-sectional-molds, means for supporting the sectionsof said hinged molds permitting them to be opened book-fashion, saidmeans including rollers connected to the respective mold sections atopposite sides of each, runways on which said rollers rest, and meansinsuring equal translatory movement of the axes of the rollers on eachof the mold sections. I i

i. kn apparatusfor treating tires compris ng, 1n combination, aplurality of molds having sections, hinged cradles secured to each ofsaid mold sections, pairs of rollers secured to said cradles with theiraxes paralled to that of the hinge, the rollers of each. pair beinglocated a greater distance apart prising, in combination, a plurality ofhinged sectional molds, meansfor supporting the sections of said hingedmolds permitting "them to be opened book-fashion,

said means including rollers sustaining the respective mold sections atopposite sides of each, runways for said rollers. and means shiftablysupported above said molds and movable lengthwise of .said' runways forclamping the molds together at a point substantially opposite. theirhinged connection.

and State of Connecticut, this 26th day of 5 HECTOR v. LOUGH.
